简单介绍
BURKERT德国进口气动式二位二通截止阀简介
Measured as overpressure to the atmospheric pressure Response times [ms]:
Opening Closing Measured at valve outlet at 6 bar and +20ºC. Pressure relief 0 90% Pressure drop 100 to 10%
cv截止阀又称截门阀，属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。，
表示阀门已达全开位置。所以截止阀的全开位置，应由阀瓣的行程来决定。

The actuator body is made out of epoxy resin.
主轴设计有双层密封件，但没有压盖。
紧凑型结构
2/2-way valve for medium up to +140ºC
The externally controlled valve is pneumatically operated. It consists of a diaphragm actuator and a 2-way valve body.
驱动装置外壳由环氧树脂构成。
主轴设计有双层密封件，但没有压盖。

我国阀门“三化给”曾规定，截止阀的流向，一律采用自上而下。
截止阀开启时，阀瓣的开启*度，为公称直径的25%～30%时.流量已达到

The diaphragm actuator moves a spindle with valve disc against a spring and switches the valve.
The spindle is designed glandless with double seal.
Technical data Body material Brass, stainless steel Inner part valve Stainless steel
Actuator Epoxy resin Seal material NBR, FKM, PTFE/FKM, EPDM, PTFE/EPDM Medium NBR

当介质由阀瓣下方进入阀门时，操作力所需要克服的阻力，是阀杆和填料的摩擦力与由介质的压力所产生的推力，
关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。
